A lot of boxing people are very shifty, and thus they tend to assume that other people are that way as well. Suppose, for example, that you go into a gym where you are unknown and let it be known that you have a boxer, say 15 years old, been training 6 months, never been in the ring, and you're trying to find him some work. They will automatically assume that you are lying- that your boxer has, in fact, had 35 amateur fights and that you are looking for some one he can smack around to build his confidence, because that is what they would do. So they'll say that they, too, have a young boxer, but in fact he was just a finalist in the regional Jr. Olympic trials...well, these things get silly.
It is best to deal with people you know, or that are known to the guy that runs the gym you regularly go to.
